Brother MFC-685cw disassemble to repair error 51

SOURCE: machine error 46

Here is the answer to the Machine Error 46 (have just fixed my own MFC210C):


Machine Error 46 – Purged Ink Box Full MFC620CN/420CN/410CN/210C and FAX2440C

The machine counts all purge (cleaning) operations in order to prevent the internal ink absorber box from overflowing with purged ink. An “initial purge”, for example, advances the purge counter by 187 + 420 = 607. When the purge counter approaches 6400, an internal "Machine Error 46" is generated. Further purge operations are prohibited, and therefore the printer becomes unuseable.

When an internal Machine Error 46 is generated, the user will see an “Unable to Clean” external message and will be unable to use the printer. The “Unable to Clean” external message can relate to many different internal error codes however.

The user can establish the internal Machine Error Code as follows: pull the mains cable out of the machine (power off), hold down the Menu/Set key, re-insert the mains cable into the machine (power on). The internal Machine Error Code will be displayed.

If there is a Machine Error 46, it is necessary to dismantle the printer, replace the ink absorber box (or possibly break the ink absorber box open and clean its absorbent sponges under a tap), re-assemble the printer and reset the purge counter to zero.


Resetting purge counter MFC620CN/420CN/410CN/210C and FAX2440C

1) Enter machine maintenance mode (on MFC210C all four photo/copy/fax/scan lights flash in maintenance mode). Care is needed in maintenance mode, otherwise critical settings may be inadvertently corrupted.

FAX models with numerical keypads: Press the Menu/Set, *, 2, 8, 6 and 4 keys within two seconds. (if you fail to complete the correct key sequence within two seconds, press the Stop key to try again).

Other (non-FAX) models: Press the Menu/Set and Black Start keys. Next press the “up arrow” key four times to enter the maintenance mode).

2) Press the 8 then 0 keys in the initial stage of the maintenance mode to call up the machine's log information list (function code 80).

3) Press the Black Start key several times to scroll through the log information list to reach the purge counter. The purge counter is the 25th item in the list.

4) Press the 2, 7, 8, and 3 keys in this order to reset the purge count to zero.

5) Press the Stop/Exit key to return to the initial stage of the maintenance mode.

6) Press the 9 key twice to return to the standby state.

Carry on printing !!

thanks.

SOURCE: How do I clear

51 error says that the purge assembly is stuck and not cycling properly. If you can power up and get the printhead to the center and unplug again, look with a flashlight in the far right corner where the printhead parks for any paper scraps or things that don't belong and remove them it might work again. Otherwise a shop repair to possibly replace the cleaning assembly.

Usually this is caused by a foreign object or debris under the printhead path, or under where the printhead "parks."

Unplug the machine. Open the cover. Check the printhead path for little bits of paper, push pins, paperclips, staples etc. Note the location of the printhead.

If the printhead is at the far left, gently slide it towards the center (do not force it). Look carefully under where the printhead was stopped for debris. Use a flashlight if necessary.

Close the cover. Plug in the unit. Try again.
